CARACAS, Venezuela — Venezuelan President Hugo Chavez confirmed late Thursday that his fourth and final round of chemotherapy was successful, reassuring supporters that his “socialist revolution” would plow ahead at full steam.

Arriving from Cuba, Chavez said that his chemotherapy treatment was completed in Havana on Wednesday. The past five days he spent on the island were “very productive, very positive,” he said, before confirming that he requires no further treatment for cancer.

The news was greeted by rounds of applause from onlookers.

“I feel like I’ve been born again,” Chavez told his followers from the International Airport of Maiquetia in Caracas, immediately after touching down on Venezuelan soil.

Scheduled television programs were interrupted as his speech was broadcast live on all national channels shortly before midnight Thursday.

The Venezuelan leader thanked his high-profile Latin American counterparts for their public support during his battle against cancer. Bolivian president Evo Morales paid an “unofficial” visit to the presidential palace in Caracas on Sept. 17, while Cuba’s former leader, Fidel Castro, dispensed political and personal advice throughout his illness.

“Now we are going dedicate our efforts to the recuperation of the physical side of things,” Chavez said.

Political regeneration was also high on the agenda, as the leftist leader assured supporters that he plans to continue in office with an eye on next year’s presidential election.

Chavez, who had a cancerous tumor removed June 20, underwent his first two rounds of chemotherapy in Havana. He concluded his third round at a Venezuelan military hospital on Sept. 2.

Despite widespread publicity surrounding Chavez’s physical wellbeing, little is known about the kind of cancer afflicting the 57-year-old president.
